To all whom t may concern.'

Be it known that we, CHARLES FRANKLIN ECKART, a citizen of the United States, and GUIDO GIACOMETTI, a citizen of Italy, residents of Olaa, in the county and Territory of Hawaii, have invented certain new and useful Improvements in Spraying-Sleds; and we do hereby declare the following to be a full, clear, and exact description of the invention, such laswill enable others skilled in the art to which it appertains to make and use the same,

This invention relates to vdevices for destroying or' checking the growth of weeds or grass by spraying the same with a solution containing arsenite of soda or other deleterious material.

Its object is to provide an eiiicient kdevice of this character, which shall beparticularly adapted to be drawn between the rows of cultivated crops, such as sugar cane, which are grown in rows, to destroy or check the growth ofthe weeds and grass growing between the said rows.

A further object is to provide means whereby this device, when drawn between Athe rows, will automatically cause a spray of the deleterious solution to be projected upon the weeds or grass growing in anyl break or opening in the said rows, 'such oc# casional open spaces in the rows usually loeing weedy.

Our device contemplates, a sled adapted tol be drawn between therows of cane or the like, a tank carried thereon to hold the deleterious solution, an air pump for obtaining and maintaining a pressure within the tank, means for projecting this solution in the form of spray on the ground over which the sled passes, arms hinged to the sled on oppo-` site sides, means for causing the arms to swing out and project 'laterally from the sled, and a nozzle carried by each of the said arms and connected to the said tank for spraying the ground under the said arms.

Both ends of the sled may be made alike, and the arms and the spraying devices may 'be'in duplicate at each end of the sled, so that the sled may be drawn in either direction between the rows, and thus prevent the necessity of having to turn the sled around. The arm on each side of that end of the sled which at the time is the forward end is hooked or pinned within the runner, while the arms on the sides of the rear end are permitted to swing. When an arm projecting'from the sled encunters the'cane or the l1ke in the row,'as the sled moves forward, the arm is pushed thereby. and caused to swing rearward toward the runner, against the action of an attached spring,l so that the spray from the nozzle carried bythe said' arm'is projected on the ground near this runner. When, however, a break or open ing occurs in a row, there being no cane or the like to interfere with the arm and cause it to swing rearward, the arm is immediatelyextended laterally from the sled by the u action of the attached spring, and consequently the spray from the nozzle supported by the armv is projected upon the weeds or grass growing in this open space in the row. The arm is thus operated automatically by interference with the growing crop, so that the spray is not projected upon the rows eX- cept when an open space occurs in the row.

In the accompanying drawings, formingv 'a part of this specification, similar characters of reference indicate corresponding yparts in all the views.

Figure 1 is a plan View of a device for the purpose described embodyin the invention; Fig. 2 is a side elevation o the same; and Fig. 3 is an end elevation of the same.

Referring to the drawings, the two run-v ners 5 are similar with both of their ends curved as shown. The middle or central portion of each of the runners 5 is filled in with wood 6 of substantially the same'thickness as the width of the runner 5. The extreme ends of these runners 5 are connected by the metal cross-bars 7, and the wooden a well known manner, lso that the sled may be drawn in eitherdirection.

The container or tank 11 is mounted on the sled as shown, This tank may be filled with the deleterious solution by removing the plug 12'. The air pump 13, operated by the hand lever 14, is provided tol produce a pressure within the tank 11. The nozzles 15 are connected by the pipes 16, providedwith the valves 17, to the tank 11, as shown. The 11o solution may thus flow from the tank 11. and issue from the nozzleslti in the form of spray which is projected downward onto the weeds or grass or ground over. which and near which the sled is drawn. vThe-issue of this spray may be regulated bylmeans of the valves 17.

A gate-shaped arm 18 is hinged on a hinge-pin 19 at each end of each of the two wooden sides 6 within the runners 5. Each arm 18 is provided with a projection 20. A tension spring 21 connects theend of each projection 20 with a cross-bar 7, so that each arm 18 is pulled by a spring 21 and when operating is swung out and projects laterally from the side of the sled. The arms 18 at one end of the sled, which at the time is the forward end, are secured within the runners 5, for example, vby means of a pin 22 passed through a hole in the runner 5 and in the arm 18. A nozzle 23 is secured to the end of each pipe 24 supported by the hingepin-'19 andby a clip 25 attached to the arm 18. Each pipe 24 is iexibly connected by ahose 26 to the pipe 16. Guard plates 27 are secured to the ends of the cross-bar 7 to protect the nozzles 23 and the pipes 24 when the arms 18 are in the non-operative position.

In operation, the tank 11 having been filled with `the deleterious solution and a pressure obtained therein by the pump 13, the sled is drawn through the cultivated 1ield between the rows of cane or the like by va mule or horse for example attached to the chain 10 at one end of the sled. By operating the valves' 17, the solution under pressure in the tank 11 is permitted to ow through the pipes 16 and issue from the rear set of nozzles 15 in a iine spray, which is projected downward onto the weeds or grass or ground over which the sled passes. The forward arms 18 are secured within the runners 5, while the rear arms 18 are allowed to swing on their hinge-pins 19. The solutionflowing from the tank 11 `through the pipe 16 also passes through the hoseV 25, the pipes 24, and issues from the nozzles 23 in a fine spray on the weeds or grass or ground underneath the same. When an arm projecting from the side of the sled encounters cane or the like in the row, as the sled moves forward, the arm is pushed and caused thereby to swing rearward on its' hinge-pin 19, against the action of the spring 21, so that the spray from the nozzle 23 carried by the said arm is projected nearthe runner 5 and not over the row nor on the caneor the like.

When, however, an opening occurs inthe of cane or the like, but will also spray 4any occasional open spaces in the rows, the arms y18 being automatically operated by interference with the growing crops as the sled is drawn forward between the rows.

We are aware that it isnot new to apply a deleterious material in' solution contained in a tank under pressure for the purpose' of destroying or checking the growth of weeds and grass; but

We claim: .j

1. Apparatus for spraying the ground between adjacent rows of ycultivated. plants with deleterious material, comprising a sled, a tank carried thereby for holding the del-- eterious material, a cross member bracing the end of the sled, an arm pivoted to each side of the sled having an inwardly directed ro'ection la s rino' inter osed between each of said projections and said cross member, la nozzle carried by each of said arms, and means to supply the deleterious material from said' tank to each of said nozzles.

2. Apparatus for spraying the ground between adjacent rows of plants with deleterious material, comprising a sled, 4a tank? extended positions whereby each nozzle may deliver the material to the groundto one sideof the sled, and means for `locking said arms in their inoperative positions in aline-` ment with the runners of the sled.

3. Apparatus for spraying the ground. be-

tween adjacent rows of plants with deleterious material', comprising a sled,` a tankl mounted thereon, a pair of swinging arms associated with each endof the sled and pivotally connected therewith, a nozzle carried by each of said arms, connections between the nozzles and the tank,means to normally yieldinglyhold said arms in extended {position, and means to lock said arms in their inoperative position in alinement with the runners of the sled whereby said sled may be drawn in either direction between the rows of plants.

j In testimony whereof we aiiix` our signatures, in presence of two witnesses.
